Recent findings indicate significant vulnerabilities in PostgreSQL due to misconfigurations that can enable unauthorized shell command execution on the operating system. The COPY SQL command combined with the pg_execute_server_program role facilitates these vulnerabilities, especially when PostgreSQL services are exposed via Kubernetes ingress. PostgreSQL is the third most targeted application among Google customers, with weak passwords being a common vector for initial access in 41% of observed compromises. Misconfigured instances, particularly manual deployments, often lack proper authentication controls, user roles, and permissions. The use of “trust” authentication allows users from any IP to connect without a password, potentially granting superuser privileges. This vulnerability can be exploited by attackers to execute malicious commands, such as downloading cryptocurrency mining software. CrowdStrike's Falcon platform provides protection against threats targeting PostgreSQL by detecting and preventing malicious activities. Best practices for securing PostgreSQL include using strong passwords, securing configuration files, enabling SSL/TLS, auditing user roles, and adopting a Zero Trust approach to access control.
